edit; did some searching and apparently you have to choose between 60Hz and 48Hz per eye.. so it's either pulldown judder or plain old flicker, then.

RealD cinemas kind of use a shutter, too, but it's located inside the projector, and runs at 144Hz. so that's 3:3 pulldown at 72Hz per eye.
no flicker and noo judder. What were the 3dtv makers thinking?

One significant advantage is that you can output true 23,976Hz, because
with a 120Hz shutter-glasses TV you'll get pulldown issues playing a 24fps 3d film.

AND, right now a setup like this is cheaper than just about any 3d-ready tv on the market.. and don't even get me started on price per inch >.<

Anyway, it's simply a matter of decoding the stream(or streams) and outputting the images for left and right to two separate X monitors simultaneously. (with of course the double subtitles that you'll need for any 3dtv too) Planar 3d displays use the same dual output btw.

No image sync or glasses control, just the two separate outputs.

Stereoscopic Player works fine, but it's not for linux and doesn't have a very sexy interface.. it's kinda like mplayerc but more grayish and boring, if it's at all possible.

btw, i think xbmc should scan the filenames for "3D" and more specifically "Half SBS" and so on, just to automagically know how it should output the file.. end users don't want to work through context menus and mark all their 3d stuff as sbs or over/under and so on

My Panasonic Viera GT25 has no problems with pulldown issues, and you can see that in several reviews of the VT25 (which is pretty much the same tv minus a few inputs on the back panel) that Panasonic has taken care of that problem quite well...

Panasonic also set up their 3d systems to handle many different variations of 3d, from SBS, over under, stereoscopic, anaglyph, etc...all selectable by remote or you can simply leave it on autodetect...the tv also does a good job of upconverting 2d to 3d, as my girlfriend found out last night the hard way when she accidentally hit the 2d-3d menu button during an episode of "16 and pregnant"...don't think she'll be messing with that feature again anytime soon, lol.

It won't do that for Half SBS and TnB files because the system thinks they are just regular 1080p files.

If you play a full SBS file on Windows XBMC (with a GT430), the TV WILL kick into 3D mode. It is like that extra high resolution "turns 3D on." This presents a problem though, as full 3D is not SBS and certain TVs (like my Samsung) won't let you change over to SBS and TnB modes once they are in "official" 3D mode. Until XBMC can play 3D content like its meant to be played (aka FFMPEG gets 3D support), half SBS and TnB files are way easier to mess with.

Your TV should have a 3D button. Just map the commands to switch 3D and SBS to a Harmony macro and you are set. Turn it to 3D content, hit one button, and show off the future to your friends.

The only real problem usability-wise in XBMC is that the menus are not 3D compatible. I am actually considering getting a Boxee Box to play my 3D content for that reason.

StarChild Wrote:120Hz is 5:5 pulldown for 24p content. So whats the issue? You don't want 24Hz on shutter-glasses, it would flicker.

Yes, 120Hz IS indeed 5:5 for 24p content. the issue is that when you play 3d content, the TV is constantly alternating between the left and right image frame on those 120Hz, so essentially, you're playing them both at 60Hz each=2:3 pulldown judder.

Refresh rates for correct 24p 3d playback on a shutter-based system has to be a multiple of 48Hz. of course 48Hz would flicker like crazy at 24Hz per eye. 96Hz will still flicker a bit for most people, and even if they don't notice it, it could probably induce headaches(like a low-refresh CRT).

Not necessary. I'm not updated how the TV handle it. But technically it's possible. If the shutter glasses work in 120Hz it's not necessary need to be on the same eye when a new frame kicks in.
Frame 1: right, left, right, left, right
Frame 2: left, right, left, right, left
Frame 3: right, left, right, left, right
Frame 4: left, right, left, right, left
and so on... This way theres no need for 3:2 pulldown.
